As I recall, this thing has no dewcap or glare shield, right? You could make a dewcap about twice the aperture in length. This would serve to keep the corrector from dewing-up, and let you spot targets close to the moon with less glare. Also, an anti-reflection coating can be done at home- it's not an evaporated coating, but a chemical surface etch. It has been in S&T and at least one other ATM-type journal, but memory fails me right now on the specifics. Chuck --- Greg Taylor <astronomus_maximus@yahoo.com> wrote:
Thanks. The reason that I was asking is that when I was testing it out on Jupiter this morning, the light from the moon reflected off of the plate, causing the field to be washed-out. (I'm somewhat astonished at how razor thin the focal plane is at f/3.64). Greg
